Zayibeth Carballo, P.E. Township of West Orange February 1, 2024 Page 2 of 4 Our technical comments on the work to be completed are as follows: During the design period, the Township Forester, John D. Linson, will identify the trees on each street by location, type, and diameter that are to be removed. This information will be included with the Contract Documents issued to prospective bidders for the bidder's use in preparing his bid for various tree removal items. Existing curb elevations will not be changed to minimize any adverse impact on roadway or private property drainage patterns. Preparation of any cut sheets or any construction stakeout will be included in the work to be bid and performed by the Contractor. Project Schedule H2M will dedicate sufficient resources to complete the design services described herein to enable the Township to advertise for bids in the winter of 2024/2025. We anticipate that the Township will award the Contract for Engineering Services in the beginning of March. Scope of Services H2M will perform the following major activities and tasks for the proposed street improvements project: Design Services Perform and prepare a topographic route survey within the project limits for the purpose of depicting existing physical surface features and developing base mapping for the preparation of Contract Drawings. The survey will include horizontal and vertical control, including setting benchmarks, and establish roadway centerline. The limits of the survey will extend up to 10 feet beyond the existing right-of-way to include trees, shrubs, walls, driveways, walks, steps, and other existing surface features. The right-of-way will be shown on the Contract Drawings based on information provided by the Township. A copy of the survey will be provided to the Township in AutoCAD format. Perform walkthrough assessment of sections of Walker Road, South Valley Road, and Rooney Circle identified in the RFP with the Township Engineer to discuss the specific improvements planned for it. Prepare Contract Drawings for the proposed road improvements. We anticipate that the following drawings will be prepared by H2M: - Cover Sheet— 1 drawing. - Key Map, Legend, and General Notes — 1 drawing. - Estimate of Quantities — 1 drawing. - Plan Drawings (scale 1" = 40' horizontal) of the sections of Walker Road, South Valley Road, and Rooney Circle indicated in

gend, and General Notes — 1 drawing. - Estimate of Quantities — 1 drawing. - Plan Drawings (scale 1" = 40' horizontal) of the sections of Walker Road, South Valley Road, and Rooney Circle indicated in the RFP — 7 drawings. - Construction Details, including granite block curbs, milling and resurfacing of roadways and driveways, concrete roadway repairs and leveling courses, curb ramps — 5 drawings. - Soil Erosion and Sediment Control Details — 1 drawing. - Traffic Control Details — 2 drawings. Contact the Township Police Department Traffic Bureau to coordinate the proposed road closures and traffic detours. Aerial imagery will be used for preparation of base mapping to show the extent of the proposed road closures and detours. Sign locations will be shown on the drawings for the
